  • data dependent logic swing internal bus architecture for ultralow power lsi s
    IEEE Journal of Solid-state Circuits, 1995
    Co-Authors: Mitsuru Hiraki, Hirotsugu Kojima, H Misawa, T Akazawa, Yuji Hatano
    Abstract:

    A reduced-swing internal bus scheme is proposed for achieving ultralow-power LSI's. The proposed data-dependent logic swing bus (DDL bus) uses charge sharing between bus wires and an additional bus wire to reduce its voltage swing. With this technique, the power dissipation of the proposed bus is reduced to 1/16 that of a conventional bus when used for a 16-b-wide bus. In addition, a dual-reference sense-amplifying receiver (DRSA receiver) has been developed to convert a reduced-swing bus Signal to a CMOS-Level Signal without loss of noise margin or speed. Experimental circuits fabricated using 0.5-/spl mu/m CMOS process verify the low-power operation of the proposed bus at an operating frequency of 40 MHz with a supply voltage of 3.3 V. >

  • Origin of the two-dimensional electron gas at the CdO (100) surface
    Physical Review B, 2019
    Co-Authors: Pip C. J. Clark, Andrew I. Williamson, Nathan Lewis, Ruben Ahumada-lazo, Mathieu G. Silly, James J. Mudd, Christopher Mcconville, Wendy R. Flavell
    Abstract:

    Synchrotron-radiation angle-resolved and core-Level photoemission spectroscopy are used together to investigate the origin of the two-dimensional (2D) electron gas on the surface of single-crystal CdO (100) films. A reduction in the two-dimensional electron density of the surface state is observed under the synchrotron beam during angle-resolved photoemission spectroscopy, which is shown to be accompanied by a concomitant reduction in the surface-adsorbed species (monitored through the O 1s core-Level Signal). This shows that surface adsorbates donate electrons into the surface accumulation layer. When the surface is cleaned, the surface conduction band state empties. A surface doped with atomic H is also studied. Here, interstitial H increases the two-dimensional electron density at the surface. This demonstrates that reversible donor doping is possible. The surface band-bending profiles, 2D electron densities, and effective masses are calculated from subband dispersion simulations.
